Fix these two compile errors on s390 which does not have HAS_IOPORT
nor GENERIC_HARDIRQS:

sound/pci/lx6464es/lx6464es.c: In function ‘snd_lx6464es_free’:
sound/pci/lx6464es/lx6464es.c:565:2: error: implicit declaration of function ‘ioport_unmap’

sound/soc/codecs/wm8903.c: In function ‘wm8903_set_pdata_irq_trigger’:
sound/soc/codecs/wm8903.c:1954:9: error: implicit declaration of function ‘irq_get_irq_data’
